It is found in most of continental Europe and the Near East. The wingspan is about 22 mm. The adults fly from late June to early August[1]. They are attracted to light.
The larvae feed on various herbaceous plants such as Galium, Taraxacum, Rumex and Thymus. Wikipedia →

Rare
Under 5% of wildlife watchers report an Ochraceous Wave sighting in Moscow on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 774th most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Ochraceous Wave in Moscow on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Ochraceous Wave sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Moscow, in our data
Moscow is the only city on Wallace's Line with enough records to rate Ochraceous Wave sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ochraceous Wave is recorded against all the insects logged in Moscow (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
